UNITED STATES EDWARD A. MINOR, OF ROCK ISLAND, ILLINOIS.

VISE.

Specification of Letters Patent.

Patented Oct. 5, 1920.

Application filed. October 31, 1919. Serial No. 334,833.

T 0 all whom it may concern Be it known that I, EDWARD A. MINOR, cltizen of the United. States, residing at Rock Island, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Vises, of which the following is a specification.

This invention relates to an improved vise and has as one of its principal objects to provide a construction wherein the coacting jaws of the vise may be swung horizontally and also rocked in a vertical plane so that universal movement of the jaws will thus be had.

The invention has as a further object to provide a vise wherein the jaws may be locked in adjusted position when swung horizontally and may also be locked .in adjusted position when rocked.

And the invention has as a still further object to provide a vise wherein the jaws may be readily adjusted with respect to each other regardless of their adjustment as a unit.

Other and incidental objects will appear hereinafter.

In the drawings:

Figure 1 is a perspective view of my improved vise,

Fig. 2 is a horizontal sectional view'taken medially through the shank of the. movable jaw of the vise,

Fig. 3 is a vertical sectional view taken centrally through the vise,

Fig. 4 is a sectional view taken at substantially right angles to the section of Fig. 3 on the line 4-i of Fig. 3,

Fig. 5 is a detail perspective view of the nut employed for coaction with the adjusting screw of the movable jaw of the vise,

Fig. 6 is a detail perspective view of the clamp employed for locking the jaws in horizontally adjusted position, and

- Fig. 7 is a sectional view taken on the line 7-7 of Fig. 3 and looking in the direction of the arrows.

In carrying the invention into effect, I

' employ a split supporting sleeve 10 provided at one side with a tangentially disposed angle plate 11 by which the sleeve may, as suggested in dotted lines in Fig. 1, be secured to a workbench. Formed on the sleeve at its ends are radial lugs 12 at the inner ends of which the confronting faces of the sleeve ends are cut away to form a vertical channel 13 having, as particularly shown in Fig. 4, a sloping bottom wall and slidable within said channel is a clamping wedge 14, the outerinclined face of which seats flat against said wall so that the inner inclined face of the wedge lies parallel to the axis of the sleeve. Formed on the sleeve at its outer edge are spaced lugs and pivoted between the lugs 12 of the sleeve is a lever 15 engaging at its inner end between the lugs of the wedge. Thus, it will be seen, the outer end of this lever may be elevated for projecting the wedge into the opening through the sleeve.

Freely received through the sleeve 10 is the stock 16 of my improved vise. This stock is, as particularly shown in Fig. 4, preferably tubular and is provided at its upper end with an annular overhanging flange 17 coacting with the sleeve for normally supporting the stock thereon. Rising from the stock above the flange 17 is a yoke having parallel side plates which, for convenience, have been indicated at 18 and 19 respectively. Carried by said yoke are the coacting jaws 20 and 21 of the vise, the jaw 20 being, in so far as the adjustment of the jaws with respect to each other is concerned, the relatively fixed jaw, and the jaw 21 the movable jaw. The base of the jaw 20 is snugly received between the side plates of the yoke and formed through the jaw base is a horizontal channel or' opening through which is slidably fitted the hollow shank 22 of the movable jaw, this shank extending laterally from the movable jaw at substantially right angles. The fixed jaw thus carries the movable jaw and pivotally supporting both of the jaws are trunnions 23 and 24: respectively, extending laterally from the sides of the fixed jaw and integral therewith. These trunnions are freely received within vertical slots 2e in the side plates 18 and 19 of the yoke so that the assembled jaws may thus be readiiy fitted upon the yoke, the trunnions resting against the bottom walls of said slots. Formed on the outer sides of said plates in concentric relation to the trunnions are annular flanges 25 and mounted upon the trunnions to freely fit within said flanges are circular stop plates 25 and 26 respectively. As will be best observed upon reference to Fig. 4L, the trunnion 23 projects entirely through the side plate 18 so that the plate 25 will not frictionally contact said side plate and engaged through the plate 25 is a machine bolt or other suitable fastening 26 threaded'axially into the trunnion 23 for securing the stop plate thereto. At its outer end, the trunion 2-1 is formed with a reduced extension 27 having fiat side faces and, as will now be noted, the stop plate 26 is formed with an elongated opening fitting said extension so that the plate is thus carried by the extension to turn therewith. Further, thls plate is mounted to frlct-ionally contact the side plate 19 of the yoke and threaded axially into the trunnion 2 1 is the shank of a clamping nut 27 coacting with the plate, this nut being preferably equipped witha hand pin so that the nut may be readily adjusted. As will be clear, the trunnions 23 and 2 1 will support both of the jaws to rock as a unit in a vertical plane upon the yoke and by manipulating the nut 27, the plate 26 may be clamped in engagement with the side plate 19 of the yoke for locking the jaws when so adjusted, At the same time, this plate 26 and the plate will coact with the flanges 25 for locking the trunnions against upward displacement through the slots 24 and consequentlylocking the jaws upon the yoke. By releasing the clamping wedge 14 so that the stock 16 may turn within the sleeve 10, the jaws may be swung as a unit horizontally when by elevating the outer end of the lever 15, the wedge may be shiftedto impinge against the stock for locking the jaws when thus adjusted. I accordingly provide an arrangement whereby universal movement of the jaws as a unit will be had and wherein the jaws may be lockedin adjusted position both when swung horizontally and when rocked in a vertical plane. Y

As will now be observed, the shank 22 of the movable jaw 21 is internally provided with a slot 28 keyhole shaped in cross section, the slot rising vertically from the lower edge of the shank and having a cylindrical upper portion from which leads downwardly through the lower edge of the shank, the reduced neck of the slot. Formed through the base of the fixed jaw from the F bottom edge thereof to intersect the horizontal channel through said jaw is a medial vertical opening and removably engaged in said opening is a nut 28 formed at its npper end with a head 29 slidably fitting within the slot 28. In this connection, it

will be observed that the side walls of the slot at the neck portion thereof are cut away at the outer end of the shank 22 in order that the head of the nut may be inserted in the slot and, of course, in assembling or disassemblingthe vise, the nut may be inserted or removed through the opening of the fixed jaw. Extending axially through 7 said slot and journaled upon the shank 22 is a screw 30 threaded through the'head 29 of the nut. This screw is provided adjacent its outer end with a head 31 confronting the adjacent end wall of the slot at its outer side and removably fitted upon the screw to confront the inner side of said end wall is a stop collar 32 coacting with the head for holding the screw against longitudinal movement. Freely mounted upon the outer end portion of the screw is a handle 33 provided at its inner end with a head 34 confronting the head of the screw. The head 3 1 carries a series of projecting pins 35 adapted to removably engage in suitable sockets 35 in the head 31 and threaded into the screw at its outer end is a thumb screw 36 adapted to coact with the head of the handlefor preventing displacement thereof from the screw 30. As will thus be clear, by shifting the handle inwardly upon the screw to engage the pins thereof in the sockets 35 the handle may be readily operated for adjusting the movable jaw 21 with respect to the fixed jaw 20, the nut 28 forming an operative connection between the screw of the movable jaw and the fixed aw. If, after adjustment of the jaws, the handle shouldproject upwardly in front of the jaws, the handle may, as will be readily appreciated, be swung downwardly to a position out of the way. In this connection, it is also to be observed that the movable jaw may be adjusted as desired with respect to the fixed jaw regardless of the horizontal adjustment of the jaws as a unit or their adjustment in a vertical plane.

In connection with the jaws 20 and 21 I provide removable jaw faces 37 provided at their inner sides with dovetailed ribs 38 removably engaging in similarly shaped slots formed in the ends of the jaws. At corresponding ends of the slots the jaws carry stop screws 39, the overhanging heads of which are each cut away at one side so that by properly rotating the screws the heads thereof may be shifted to confront the adjacent ends of the ribs for locking the jaw faces against displacement or may be shifted to clear the ribs so that the jaw faces .may be removed. As particularly shown in Figs. 1 and 3 of the drawings, the jaw faces are formed with a plurality of vertical. and horizontal channels 10 for receivin difierent sized pipe. Several sets of jaw races of different type may be provided to be interchangeably used as desired.

Having thus described the invention, what is claimed as new is: j

1. A vise including a relative fixed jaw 7 provided with a channel therethrough and aw to project into said shank coacting with said screw whereby the screw may be operated for adjusting the movable jaw with respect to the fixed jaw, the nut being removable through said opening.

2. A vise including a stock, a relative fixed jaw, a movable aw carried by the fixed jaw, means for adjusting the movable jaw with respect to the fixed jaw, the fixed jaw being provided with lateral trunnions adjustably supporting the fixed jaw to rock upon the stock whereby the jaws may be adjustably rocked as a unit, and means carried by one of said trunnions to operatively coact with the stock for locking the jaws in adjusted position when adjusted as a unit.

3. A vise including a stock provided with a yoke, a relatively fixed jaw, a movable jaw carried by the fixed jaw, means for adjusting the movable aw with respect to the fixed jaw, the fixed jaw being provided with trunnions coacting with the sides of the yoke whereby the jaws may be adjustably rocked as a. unit upon the yoke, a clamping plate carried by one of said trunnions, and a nut adjustable upon said trunnion to coact with the plate for binding the plate in engagement with the adjacent side of the yoke and locking the jaws in adjusted position when adjusted as a unit.

4. A vise including a stock provided with yoke plates, the plates being formed with flanges and having slots therein, coacting operatively connected jaws, one or" said aws being provided with trunnions removably engaged in said slots for pivotally supporting both of the jaws, and stop plates carried by said trunnions to coact with said flanges for locking the trunnions within the slots.

5. A vise including a stock provided with yoke plates having slots therein, coacting operatively connected jaws one provided with trunnions removably engaging in said slots for pivotally supporting both of the jaws, and coacting means carried by the trunnions and said plates respectively locking the trunnions within the slots.

In testimony whereof I afiix my signature.
